SOLE-PRESSING MACHINE.

Application filed May 18, 1903.

To all whom it may concern:

Be it known that I, ERASTUS E. WINKLEY, a citizen of the United States,residing at Lynn, in the county of Essex and State of Massachusetts,have invented certain new and useful Improvements in Sole-PressingMachines; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

The present invention relates to sole pressing machines and moreparticularly to that class of sole pressing machines by which the soleof a shoe is subjected to a rolling pressure between a'jacl: upon whichthe shoe is supported, and a suitably shaped form. Such machines are nowextensively used for leveling the soles of boots and shoes, that is, forsubjecting the soles after being permanently attached to the other partsof a boot or shoe to pressure in order to remove any inequalities and togive the proper shape or curvature.

Sole pressing machines by which the sole of a shoe is subjected to arolling pressure are commonly provided with a plurality of shoesupporting jacks and cooperating sole pressing forms, two jacks and twocooperat ing forms being usually provided. The mechanism for actuatingthe jacks and forms is arranged to move the jacks alternately from aposition at the front of the machine in which shoes can be readilyremoved t'rom and placed upon the jacks, which position is termed aposition of presentation, to a position to cooperate with the forms inpressing the soles of the shoes, which position is termed a position ofpressure. In all sole pressing machines which are adapted to exert arolling pressure upon a sole of a shoe the jacks and forms have beenpermanently connected to their actuating mechanism, and where a singlemachine has been provided with two jacks and two cooperating forms ithas been necessary to stop the machine with one jack in a position ofpressure and the other jack in a position of presentation in order toallow the operator to remove a shoe, the sole of which has been leveledfrom the jack in a position of presentation and place another shoethereon. The operator has thus been obliged after having placed a shoeupon the jack in the position of presentation to Wait while this jack isSpecification of Letters Patent.

moving into a position of pressure and the other jack is returning froma position of pressure to a position of presentation. During the greaterportion of the time that the machine is in operation, therefore, theoperator is idle. l urthermore, since the machine is necessarily stoppedduring the time the operator is employed in removing a shoe from the ackin the position of presentation and placing another shoe thereon, theoperator 1s not obliged to keep pace with the operation of the machine,the speed at which the machine is operated being entirely dependent uponthe will of the operator.

One of the objects of my invention is to provide a sole pressing machinecomprising a plurality of acks and cooperating sole pressing forms andmeans for actuating the jacks and forms to subject the soles of shoessupported upon the jacks to a rolling pres sure in which the jacks andforms shall be so actuated that the operator will be able to remove ashoe from one of the jacks and place another shoe thereon while anotherjack and its cooperating form are being moved to level the sole of ashoe and to return the jack to a position of presentation.

With this object in view, a feature of my invention contemplatesproviding a sole pressing machine comprising a plurality of jacks andcooperating forms with a common actuating mechanism acting to move eachjack and its cooperating form when connected therewith, to subject thesole of a shoe supported upon the jack to a rolling pressure, and meansfor connecting each jack and form to such common actuating mechanism andfor disconnecting them therefrom. By providing means for connecting eachaclr and form to the common actuating mechanism and for disconnectingthem therefrom, one jack is allowed to remain in a position ofpresentation While another jack is being moved from a position ofpresentation to a position of pressure and being returned to a positionof presentation. The operator is thus enabled to devote his entire timeto the replacing of the shoes upon the jacks and is not compelled towait idly for any of the operations of the machine to be completed.Furthermore, it is not necessary to stop the machine with a ack in aposition of pressure and the machine can be so speeded that the timerequired for removing a shoe from a an; and placing another shoe thereonis that con-' Patented Aug. 24:, 1909.

sumed by the machine in moving a jack from a position of presentation toa position of pressure and returning it to a position of presentation.The operator is thus obliged to 5 keep pace with the machine or allowthe machine to remain at restwith the jack in a position of presentationfor a noticeable length of time.

I am aware of the fact that it has been proposed to place two solepressing machines side by side in a single frame, each machinecomprising a jack, a cooperating form, and means for actuating the jackand form to subject the sole of a shoe supported upon the 'ack to arolling pressure, and that it has een proposed to operate these machinesalternately, the operator removing a shoe from the jack of one machineand placin another shoe thereon, while the other mac ine is inoperation. My invention is clearly distinguished from such anarrangement in that it contemplates the use of a common actuatingmechanism for all the jacks and forms, the jacks and forms and theiractuating mechanism constituting a single organized machine asdistinguished from a number of separate and independent machines.

Sole pressing machines by which a'rolling pressure is exerted upon thesole of a shoe are usually constructed to press the sole of the shoetwice, one pressure being produced by the inward movement of the jackand form, and another pressure bein produced during the return movementof t e jack and form to bring the jack into a position of presentation.It is often found desirable, however, to subject the sole to a greaternumber of pressures in order to properly beat out or level thesole. Inmany machines this is accomplished by starting and stopping the machinea number of times without removing the shoe from the jack, and certainmachines have been devised by which the jack and form are automaticallyand continuously moved to produce this result. So far as I am advised asto the state of the art, no means has been provided for varying thepressure exerted upon the sole during the successive pressingoperations, whether the sole is subjected to two or a greater number ofpressures, and an object of my invention is v to provide means forvarying the pressure so as to render the successive pressing operationsmore effective.

With this object in view a feature of my invention contemplatesproviding a sole pressing machine comprising a jack, a cooperating form,and means for actuating the jack and form to subject the sole of a shoesu ported upon the ack to a plurality of r0 ling pressures, with meansacting automatically to increase the pressure exerted upon the sole of ashoe during successive pressing operations. By providing such means theamount to which the sole is compressed during each pressing operation isautomatically taken up and the sole is more quickly and certainly beatenout or leveled. Also t 1e use of an excessive initial pressure whichwould tend to blacken or otherwise mar or injure the leather is renderedunnecessary as a comparatively light pressure can be first applied andthis pressure increased during successive pressing operations. As tothis feature of my invention I desire to state that it may be embodiedin any form of sole pressing machine comprising a shoe supporting jackand a cooperating form arranged to. subject the sole of a shoe supportedupon the jack to a rolling pressure, whether such ma- 30 chine isprovided with a single jack and its cooperating form or with a pluralityof jacks and forms.

My invention is primarily intended as an improvement upon the well-knownTripp 35 Giant leveler machine Which is illustrated and described inUnited States patent to Tripp, No. 296,486, April 8, 1884, and themachine which I have illustrated in the drawings accompanying thisapplication as embodying my invention in its preferred form is similarin many respects to the machine disclosed in said patent. In thepatented machine the jacks and forms are pivotally mounted and each jackand its 00- operating form is oscillated to exert a rollin pressure uponthe sole of a shoe supporte. upon the jack. In the patented machine eachack and form is stopped when the jack is in a position of pressure andalso when the jack is in a position of presentation. Inthe machineillustrated in the drawings accompanying this application, each jack andform 1s stopped only whenthe jack is in a position of presentation,mechanism being provided which acts continuously to impart to the jackand form relatively long oscillating movements from and toward theposition of resentation and intermediate-shorter oscilating movements.So far as I am advised of the state of the art, I am the first toprovide mechanism for so actuating a pivotally mounted jack and itscooperating form and I therefore consider a feature of my invention toconsist in providing a sole pressing machine comprising either a singlejack and a cooperating form or a plurality of jacks and forms, with suchmechanism.

In the machine disclosed in the drawings accompanying this application,the mechanism for actuating the jacks and forms comprises a drivingshaft similar to the driving shaft of the patented machine, thedirection of rotation of which is reversed in order to reverse themovements of the jacks and forms.

A feature of my invention consists in providing means actinautomatically to reverse the direction 0 rotation of the driving shaft,whereby the machine continues in oporation until a jack and form ismoved toward the position of presentation and in providing means forstopping the jack and form with the jack in a position of presentation.

Another feature of my invention consists in varying the number ofrotations of the driving shaft in each direction whereby relative longoscillating movements are imparted to a jack and form from and towardthe position of presentation and intermediate shorter movements.

Other features of my invention consist in certain devices, arrangements,and combinations of parts hereinafter described and claimed, theadvantages of which will be obvious to those skilled in the art.

Having thus indicated the nature and scope of my invention, I will nowproceed to describe the preferred form thereof illustrated in theaccompanying drawings, it being understood that the various features ofmy invention are not limited to the par ticular machine illustrated nor,except as defined in the claims, are they limited to any particularconstruction or arrangement of parts.

Referring to the drawings, Figure 1 is a View in side elevation of thecomplete machine; Fig. 2 is a view in front elevation of the machineshown in Fig. 1 with parts removed; Fig. 3 is a view in horizontalsection on the line 33, Fig. 1, and Figs. t and 5 are detail views ofthe mechanism for reversing and stopping the driving shaft of themachine.

The machine illustrated in the drawings is provided with two ache andtwo cooperating forms, the aclrs and forms being pivotally mounted andso arranged that when either jack and its cooperating form areoscillated the sole of a shoe supported upon the jack is subjected to arolling pressure. The means for oscillating the aclis and formscomprises a driving shaft and suitable connections between the drivingshaft and the acks and forms. The driving shaft is rotated alternatelyin opposite directions and the connections between the driving shaft andthe acks and forms are such that the direction of the movement of thejacks and forms is changed with each reversal in the direction ofrotation of the driving shaft. Means are provided for connecting eachjack and its cooperating form with the driving shaft and fordisconnecting them therefrom so that one jack and its cooperating formcan be operated to level the sole of a shoe supported upon the jackwhile the other jack and form remain in a position of presentation, thatis, in a position which allows the operator to readily remove a leveledshoe from the jack and place another shoe thereon. Mechanism is providedwhich acts automatically to reverse the direction of rotation of thedriving shaft and to finally stop the driving shaft with the jack andform which has been connected thereto in a position of presentation.Means are also provided for automatically disconnecting the jacks andforms from the driving shaft as they reach the position of presentationso that when the machine is at rest both jacks and their cooperatingforms are disconnected. Means are also provided by which the number ofrevolutions of the driving shaft in each direction is varied, wherebyeach jack and form when connected to the driving shaft are given a longoscillation from a position of presentation to a position of pressureand then a number of shorter oscillations sufficient in extent tosubject the sole of a shoe supported upon the jack to a number ofrolling pressures and then finally a relatively long oscillation to aposition of presentation. In order to vary the pressure exerted upon thesole of the shoe during the successive pressing operations to which thesole is subjected mechanism is provided for forcing the form toward thejack with an increasing pressure during successive oscillations of thejack and form.

Referring to the drawin s 1 indicates arms pivoted at 2 in the upperportion of the machine frame 3 upon which arms the sole pressing formsare mounted.

4 indicates arms pivoted at 5 on the frame of the machine beneath thearms 1 and constructed to receive the shoe supporting lacks. Thearrangement of the arms 1 and 4 is such that the jacks and forms mountedthereon subject the soles of shoes supported upon the jacks to a rollingpressure when the arms are oscillated. Toothed sectors 6 are attached toor formed integral with the arms which mesh with worms 7 upon verticalshafts 8 journaled in the rear portion of themachine frame.

Motion is transmitted to the vertical Worm shafts 8 by gears 9 thereuponmeshing with a gear 10 on a vertical shaft 11 which is connected bybeveled gears 12 with the driving shaft 13. The driving shaft isactuated by pulleys 14 and 15 connected with a suitable source of powerso as to be continuously rotated in opposite directions. The pulleys areloose on the shaft 13 and are arrangedto be moved transversely intoengagement with clutch members 16 secured to the shaft.

A horizontal shipper rod 17 slides in bearings 18 on the frame andcarries split collars 19 engaging annular grooves in the hubs of thepulleys. This shipper rod is moved to the right or left at the propertimes during the operation of the machine to bring the ipulleys 14 and15 alternately into engageiment with the clutch members 16 to reversethe direction of rotation of the driving shaft and is also moved todisconnect both pulleys from the clutch members 16 to stop the machine.The shipper rod is actuated to reverse the direction of rotation of thedriving shaft by a cam shaft 20 journaled in the frame of the machinetransversely to the driving shaft, and suitable connections be tween thecam shaft and the shipper rod. The dam shaft 20 is intermittentlyrotated from the driving shaft by a traveling nut 21 engaging a threadedportion of the driving shaft and connections between the nut and the camshaft. These connections comprise a link 22 which connects the nut witha lever 23 pivoted at 24 to the frame of the machine, a link 25connecting the lever 23 to a bell crank lever 26 pivoted to the frame ofthe machine at 27, links 28 connecting the opposite ends of the bellcrank lever with distance arms 29 pivoted on the cam shaft 20, pawls 30mounted upon the distance arms and a ratchet wheel 31 engaged by thepawls fixed to the cam shaft. These connections are so arranged that thecam shaft 20 is intermittently rotated as the nut 21 travels back andforth on the threaded portion of the driving shaft, one pawl 30 being inengagement with a tooth of the ratchet wheel when the nut is travelingin one direction and the other pawl being in engagement with a tooth ofthe ratchet wheel when the nut is traveling in the opposite direction sothat the cam shaft is moved forward a step during the travel of the nut21 in each direction. A cam disk 32 secured to the cam shaft 20 isprovided with a cam groove 33 which is engaged by a stud or roll on ashipper arm 34 pivoted at 35 to the frame of the machine. The upper endof the arm 34 has a pin and slot connection with a collar 36 looselymounted upon the shipper rod 17. Springs 37 and 38 surround the shipperrod and are interposed between the loose collar 36 and collars 39 faston the shipper rod. The cam disk 32 is also provided with a series ofcam projections 40 upon the opposite face to that in which the camgroove is formed Wl'llGll are arranged to engage a roll or stud on. thelower end of a locking lever 41 pivoted at 42 to the frame of themachine. The upper end of the locking lever is provided. with a slotwhich receives a pin 43 projecting from the shipper rod 17. The shape ofthe cam groove 33 and the arrangement of the cam projections 40 are suchthat during the rotation of the cam shaft 20 the shipper rod is heldstationary by the engagement of one of the projections 40 with the studon the lower end of the locking lever 41 while the shipper arm 34 isbeing actuated by the cam groove 33 to move the collar 36 to the rightor to the left as viewed in Fig. 5 so as to compress one of the springs37 and 38.

After one of the springs has been com-' pressed 'tllQ'COlltlXlUGdrotation of the cam' shaft moves the projection 40 out of engagementwith the stud on the lower end of the her of intermediate shorteroscillations.

locking lever 41 so that the compressed spring is allowed to act to movethe shipper rod 17 in a direction to reverse the direction of rotationof the driving shaft.

As I have stated the machine shown in the drawings is provided withmeans for varying the number of rotations of the driving shaft in eachdirection in order to impart relatively long oscillations to the jackand form connected to the driving shaft from and toward a position ofpresentation and a nurjps shown in the drawings (see more particularlyFig. 4) these means comprise a cam disk 44 fixed to the cam shaftprovided with a cam groove 45 which engages a roll or stud on one end ofalever 46 pivoted at'47 to the machine frame. The other end of the lever46 is connected by means of an adjustable link 48 to the link 25. Thelink 25 is connected to the lever 23 by means of a pin assing through aslot in the lever. The s a e of the cam groove 45 is such that duringthe greater portion of the revolution of the cam shaft 20 the pin in thelink 25 is held raised in the slot of the lever At one point in therevolution of the cam shaft 20, however, the pin in the link 25 is heldin a lower position in the slot of the lever 23. MV hen the pin of thelink 25 is in its raised position it will be seen that a shorter travelof the nut 21 is required in order to turn the cam shaft 20 through adistance corresponding to the distance between two of the teeth ofratchet wheel 31 than is required when the )in in the link 5 is in itslowered position. When the pin is in its lowered position. therefore,the driving shaft will be allowed to rotate through greater number ofrevolutions before the shipper rod is actuated. The final longoscillation imparted to the jack and form connected to the driving shaftbrings the jack and form into a position of presentation, and when theyreach this position the rotation of the driving shaft is automaticallystopped. To this end the nut 21 is rovided with a lateral cam projection49 w iich is arranged to engage a detent 50 (see more particularly Fig.3) and move it into a position to engage a collar 52 fast on the shipperrod 17. The detent 50 is so arranged that during the short travelingmovements of the nut 21 it is not engaged by the cam projection 49 butis only engaged at the end of the long travel of the nut toward the leftas viewed in Fig. 4. \Vhen the collar 52 of the shipper rod 17 isengaged by the detent 50 the rod is held in a position in which bothdriving pulleys rotate loosely upon the driving shaft. In order to allowthe detent 50 to be removed from the path of the collar 52 when it isdesired to start the machine into operation it is mounted upon an arm 51fixed to a rock shaft 53 which can be actuated from either of twotreadles 54 carried by 1n in treadle levers 55 pivoted at 56' uponopposite sides of the machine frame. The inner ends of the treadlelevers are connected by means of links 57 (see Fig. 1) to vertical rods58 mounted in bearings 59 in the frame of the machine and passingthrough openings in lugs 60 projecting from arms 61 secured to the rockshaft 53. When either rod 58 is raised by de ressing one of the treadlesa collar on the ower end of the rod engages a lug 60 and rocks the shaft53 in a direction to remove the detent 50 from the path of the collar 52on the shipper rod. The sliding engagement of the rods 58 with the lugs60 of the arms 61 allows the rock shaft to be actuated by either treadlewithout moving the other treadle or the rod 58 connected therewith. Thedetent 50 is normally held in the path of movement of the collar 52 onthe shipper rod by means of a coiled spring 62 (see Fig. 3) surroundingthe rock shaft 53 and having one end secured to the frame of the machineand the other end secured to the hub of arm 51.

In order to allow either jack and its 00- operating form to be connectedto and disconnected from the driving shaft the gears 9 on the verticalworm shafts 8 are mounted to rotate freely thereon and are provided withclutch members 63 adapted to be engaged by clutch members 65 splined onthe shafts. (-oiled springs 66 surrounding the shafts 8 and interposedbetween fixed collars on the shafts and the clutch members 65 tend tomove the clutch members 65 into engagement with the clutch members 63.The clutch members 65 are moved out of engagement with the clutchmembers 63 by means of split collars 67 engaging grooves in the clutchmembers 65 secured to vertical rods 68 mounted to slide in bearings 69in the frame of the machine. Upon the lower ends of the rods 68 latches70 are pivotally mounted which are normally held in line with the rodsby means of the springs 71. The lower ends of the latches are arrangedin the path of movement of stop pins 72 projecting from the sectors ofthe jack supporting arms 4. The stop pins 72 are so arranged that whenthe jacks are in a position of presentation the stop pins are inengagement with the lower ends of the latches 70 and hold the rods 68raised with the clutch members 65 out of engagement with the clutchmembers 63. Each jack and its coperating form is, therefore,automatically disconnected from the driving shaft when the jack returnsto a position of presentation, and when the machine is at rest with bothjacks in a position of presentation both jacks and their coperatingforms are disconnected from the driving shaft. The acks and theircooperating forms are connected to the driving shaft by means of thevertical rods 58, the upper ends of which are beveled and arranged toengage stems 79 attached to the pivoted cam followers 80 carrying camrollers 81 engaging earns 82 on the pivot shafts of the arms 1. Theearns 82 are actuated during the oscillating movements of the arms 1 bymeans of spring-pressed pawls 83 mounted upon the arms which arearranged to engage ratchet wheels 84 attached to the cams. The tensionof the springs 77 and consequently the pressure exerted upon the sole ofthe shoe being operated upon is thus automatically increased during thesuccessive pressing operations to which the sole of the shoe issubjected. The cams 82 may be held from movement during the forwardmovements of the arms 1 in any suitable manner. In the constructionillustrated this result is accomplished by the friction between the camsand the pivot shafts.

While at rest the parts of the machine assumo the followingp0sitions:-lhe arms 1 and 4 are in their extreme forward position withthe jacks and forms thereon in a position of presentation. The stop pins72, engaging the latches 70 maintain the rods 68 in raised position andthe driving clutch members 63, 65, out of engagement. The stud on theshipper arm 34 is at one of the high points of the cam groove 33, sothat the arm, inits extreme left hand position as viewed in Fig. 5compresses the spring 37 which tends to throw the shipper rod to theleft. The pin on the locking arm 41 is opposite a space between theprojections 40 so that the locking arm does not prevent the shipper armfrom moving but since the nut 21 is in its extreme left-hand positionthe cam projection 49 engages the detent 50, and the latter engages thecollar 52 on the shipper rod and holds it in a medial position so thatboth pulleys revolve loosely upon the driving shaft. The low oroperative portion of the cam groove 45 engages the stud on the lever 46and the link 25 is in its lowered position, the sliding pin engaging thelower part of the slot in the lever 23.

The 0 eration of the machine is as follows e operator after placing ashoe on one of the jacks, depresses the treadle on that side of themachine. The link 57 and rod 58 connected with that treadle are raised,the incline on the rod engages the latch pin 73 and trips the latch outof engagement with the stop pin 72, and the clutch member 65 is thrownby its spring into engagement with the member carried by 1 the gear 9.These operations connect the 1 jack and its cooperating form to thedriving shaft. During the de ression of the treadle the shaft 53 isrocke and the detent 50 is removed from engagement with the collar 52.The shi per rod 17 being thus released is forced to t e left by thespring 37 and one of the pulleys is movedinto engagement with a clutchmember 16. The arms 1 and .4 are I oscillated backward and the jack andform press the sole by a rolling movement. As this movement of the armsis occurring the nut 21 is moved toward the right as viewed in Fig. 4 bythe screw thread. By means of the connecting mechanism the be 1 ver 26is oscillated and the lower pawl rotates the cam shaft 20 in thedirection of the arrow. The stud on the ship or arm passes from a hlghto a low place 111 t e cam groove 33, the ship or arm 34 moves towardthe right, and tie spring '38 is thereby com pressed, tending to movethe shipper rod 17 This tendency is opposed by the locking arm 41, thestud thereon being engaged by the outside surface of one of the I Assoon as the lever 23 has 1 completed its throw and the ratchet 31 has ibeen advanced one tooth the locking arm is released and the shipper rodmoves to the i to the right.

right under the influence of the spring 38. The direction of rotation ofthe driving shaft is thus reversed and the arms 1 and 4 are oscillatedforward. The cam shaft 20, however, continues to turn in the samedirection, and the shipper arm 34 compresses the spring 37. The stud onthe locking arm engages the inside surface of a rejection 49, thereby din its right hand pof sition until the arms 1 and 4 have completed Theseoperations redet-ermined number of holding the shipper ro their forwardmovement. are repeated a times, fixed by t e number of teeth on theratchet wheel 31.

pression on the cam groove 45 engages the stud on the lever 46, and thelink 25 is lowered. This permits the nut 21 to travel farther than usualto the left, and the arms 1 and 4 are oscillated forward to the positionof presentation. Just before the shipper rod is operated the nut engagesthe detent 5'0, and the latter arrests the shipper rod, when operated,in its medial position, both pulleys I; being disengaged, and themachine comes to crank le-' rest. Simultaneously the stop-pin 72 engagesthe latch 70 and disconnects the c utch members and 63 leaving all theparts in their initial position. During the oscillations of the arms 1and 4 the pawl 83 rotates the ratchet 84 and cam 82, thereby increasingthe pressure exerted by the spring 77 as the sole is reduced inthickness during the successive pressing operations.
